The function to show current file's full path in mini buffer

Question

I need to get the full path of the file that I\'m editing with emacs.

• Is there a function for that?
• If not, what would be the elisp function for getti

Answer 1

Can I copy the path name to System(OS)'s clipboard, not the kill ring so that I can use the info with the other apps?

You can if you shell out to something like xclip (Linux), pbcopy (Mac), putclip (Cygwin).

I personally use wrapper scripts c and p for copy and paste respectively, the first reading from standard input, the latter writing to standard output. That way, this works on all my development platforms:

(shell-command (format "echo '%s' | c" buffer-file-name))

I find this more reliable and configurable than using the Emacs clipboard support. For example, my c command copies the input to all 3 clipboards on Linux (primary, secondary, clipboard), so I can paste with either Ctrl-V or middle click.
